. The operation is as follo'ws :The fuel, such as coal, is deliveredy eithen manually lor by conveyer to the hopper* 29 where it drops throughthe passages 284 into rthe interior of themember. 'Then by rotating either vor'- vboth 'of the handlesBO,l in a; clockwisediec'- tiony as viewed in Fig. Land inthe direction fof the arrow, Fig. 2, the circumferential opening in the memberfQ will come oppo-fv site' the passage 20 in lthejmemberfQQ allowing thecoal or fuel to drop-'through the chute 418 into the casi-ng 8, 9, thel passage 28 v,being simultaneously closed-.by member 25.

' One` chute 18 delivers fuel to one side of the- ;disk 47 while the other delivers fuel in,si mi' lar manner to the other side of 'the disk 4 7; The motor lll having been started, the. shaft ,'37 is rotated in the direction ofthe arrow indicated in Fig. 2 and in consequence the scoopshaving theirreceiving ends: in the right hand compartment, Fig. .3, ick up the fuel, and in a measure reducet lesiz'esof'4 itsvpieces, and carry it around in the direc tion of the arrow until the opening between f the points 54, is reached when thefuel is thrownoli by each of the scoops from they front end of each scoop in'tothe `lire box.

l Similarly fuel vdelivered to the othercompartment ofthe chamber 8, VE) 'is picked up .and delivered into the lire bei: by the scoops having their receiving openings'in that com- -partmenla The shapeof thescoopsis Isuch.

that little or 'no coal can escape from one ried yaround to the .point ofdelivery into the4 fire box. The ooalfrom one 'compartment ofl side ofthe fire boxwhile thecal from the i compartment into the other, but must'be carthecasing 8, 9 is delivered principally to onev other compartment is delivered principally to-the other side ofthe fire box, the two sets goflscoops delivering two streams of .fuel 4 crossing eachother. To direct the streams i i ofcoalor fuel transversely or laterallyacross j the fire box the operator grasps the handles- 42 and rotates thefyoke 40 and the shaft 37 andthe disk 47 and scoops 48 in a horizontal' l planewhil'e running, with theresult that the turnA ofv the handles 30 to. the positionsi shown,.more coal will yagain be delivered into i I `fuel is deliveredto all parts of the Ifire box,

By my arrangement ofthe disk 47 and the scoops, 'as herein described, thesize or' the jstoker, lpt trticularl'y yin- .direction parallel lwith 4 the shaft 37, is shorter than'if xthe each otherLmoreor 1 ess,.tcn di`ng to more. uni` V form listributiomof' fuel inthe fu'e box.4 1t is'to heunderstood howeverfthat myfinven'- tion' 4is not limited structure except vwhere so expressl stated. 1 1 Due to. theiflexlble shaftingor' universal couplingl arrangement-betweenfthe Shaft and the gear 57, the rgear '39 v I 'emain's in mesh x with. thegear 57 y'and in" consequence'the shaft -37 and'fthe ,scoops .continue'to bel/rotated bythe motor M #irrespectivefof fthe osition to which, "the" shaft ,37- may fhaye fact the shaft37zinlsuch movement rotates .f about the geometriciv center 'of the spherical c asing and'in consequence, to ,whatever 'position the shaft 37 may. be moved, the vscoops 48 maintaining their relative `position kvwith v.respect to the-stationary'and inner wall of 'the spherical casing.

' From the above description it is apparent` lthat I have provided a Stoker which will deliver fuelV transversely to the lire box to any part thereof that it willdeliver to the rear 'orffrlot end of the re'box as well as to the more remote portions' thereof; with` out necessity of reversing or otherwise op; erating upon the rotating member, and that delivery laterally of the' tire box .is-` con trolled by shifting the Stoker while running. And it is further vapparent.` that the yStoker 'may be swung away from the furnace ywall or plate 'or' fire box lupon thehinges without disturbing the power connections or the coal feeding apparatus. And it isfurther apparent that when in position for stoki'ng the Stoker acts as a closed door tothe fire' box, there ybeing no substantial passages `to permit'ingress of air through the fire door 'abovefthe fire. f

While I have herein shown the casing8, 9 as spherical in shape, especially with respect, to the interior thereof. yit is' te be understood that the chamber needl not he completely spherical as shown` ybut maybe more or less flattened orfothorwise Shaped, particularly at the ends of the diameter cerrespondingwith the shaft airis. And it is to be further..understood that my 'invern' tion is not limited' to a spherical shaped chamber or Casingexcept where so pointed i 'out in tlie'claims.
